    Sammanfattning : IPCC reported in its climate change report 2013 that the atmospheric concentrations of the greenhouse gases (GHG) carbon dioxide (CO2), methane, and nitrous oxide now have reached the highest levels in the past 800,000 years. CO2 concentration has increased by 40% since pre-industrial times and the primary source is fossil fuel combustion. LÄS MER

  2. 2. Collaborative development of resource efficient district heating in Sweden

    Författare :Sofia Persson; Olof Hjelm; Sara Gustafsson; Mikael Ottosson; Linköpings universitet; []

    Sammanfattning : An increased recovery of excess heat from industrial processes and thermal power generation could significantly reduce energy demands. Industrial excess heat-based district heating systems are generally considered resource efficient because they reduce the use of fossil fuels and the emissions of greenhouse gases. LÄS MER
